Questions about reading converted data in ADS1298

Other Parts Discussed in Thread: ADS1298

Hello, 

I'm confused about to transfer the data converted by ADS1298, and datasheet can not clarify me.

Assuming  RDATAC mode and reading converted data from Channel 1 and Channel 2:

1) If I want to retrieve data only from CH1 and CH2, do I must transfer the data from all 8 channels of ADS ?

2) If I transfer data only from CH1 and CH2, do I need to flush the ADS buffer, or can I read both channels and ignore the remaining data transfer?

3) Assuming that a DRDY happens, if I do not transfer the converted data, in the next DRDY the previous data will be overwritten with the new converted data?

Thanks in advance.

Att,
